KEKUATAN TEKAN DAN RASIO POISSON KAYU PANGSOR (FICUS CALLOSA WILLD) DAN KECAPI (SANDORICUM KUCAPE MERR)
ABSTRACT: Pangsor (Ficus
callosa WILLD) and kecapi (Sandoricum kucape MERR) are usually planted in
garden and rural forest. The objective of this study was to determine its
specific gravity (SG), maximum crushing strength (σc//), longitudinal modulus
elasticity (EL), and Poisson’s ratio (n).
The compression test was
conducted referring to ASTM
D143-94(2000) using UTM Instron 3369 which is equipped with two biaxial clip on
extensometers. The result showed that
vertical and horizontal position of wood in the trees statistically significant
influenced on SG and σc//. Horizontal
position in Pangsor wood affected its EL, but the other position in both
species were not significantly different.
There were poor correlations between SG with EL and σc//. Poisson’s ratio value of both woods were in
a range 0.0045 – 0.275 for longitudinal-radial direction (nLR), and 0.0151 –
0.1289 for longitudinal-tangensial direction (nLT).
